James is preparing three solutions of salt water. each of the solutions has the same amount of water in the beaker and a different amounts of salt. in the first beaker, there is one scoop of salt in the beaker. the second beaker has two scoops of salt. the third beaker has three scoops of salt. which of the beakers is the most concentrated solution?

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
